River
Content Expansion 1 is activated on EU #1. It is a guarded content layer over unchanged Worldgen V4, not another biome or generator profile.
See Resources by Biome for the content-layer sources.
EU #1 uses Worldgen V4. Its environments are Plains, Forest, Desert, Swamp, River, Sea, Ocean and Caves. Terrain, water depth and resource placement follow the authoritative server generator.
Water regions: Rivers stay inland and meet the coast. Below sea level, Sea or Ocean takes precedence, including swimming depth and fishing catches. Rivers do not form freshwater corridors across open marine water.
Shallow water channels and their banks. Actual water depth determines swimming, fishing and boat access.

Terrain and presentation
Section titled “Terrain and presentation”#3eb0c8Base colors come from the game renderer. Gentle, stable tile noise adds shade variation without flicker. Plains keeps fewer trees and more open, flowery space; Forest keeps its denser tree cover.
Resources and travel
Section titled “Resources and travel”See boat controls and oxygen and hazards. Boats, swimming and fishing use actual terrain and depth.
Wildlife and threats
Section titled “Wildlife and threats”- Marsh Leech — actual water tiles only
